library in masm

library in masm

Hi, I have an assignment which is to build a library of some routines in assembly. Does anybody know how the main program (that calls the routines) and the program (library
file) which includes the routines sould be?I mean their syntax. I use masm611 and i made a library file with the ms-lib utility, but when i use ML to assemble the main programm the linker finds problems in the lib file. When i assemble the routines .asm file there are no errors.Also when i make the library with lib there are no error messages. I just wonder if there are some directives which ignore.Please i need help !!!

RE: library in masm

When i try to compile the main program that calls routines from the libray i get an "error A2206: missing operator in expression" for the programm line of the call instruction. The lib file is put in the lib directory of masm611. I used the public directive with no results at both modules. Can anybody show me a working example of two programms, one for the library and one for the main programm that calls routines from the library? Please help.

RE: library in masm


I hope this will work with MASM611.

This is a LIB example. Name the file as "msgbox.asm"

    .model flat, stdcall
    option casemap :none   ; case sensitive

    include \masm32\include\windows.inc
    include \masm32\include\user32.inc

    includelib \masm32\lib\user32.lib

  MBox proc MB_Message:LPSTR, MB_Title:LPSTR
    invoke MessageBox, NULL, \
      MB_Message, MB_Title, MB_ICONINFORMATION
  MBox endp

Build it using this command (change the masm32 path to your masm folder) :
c:\masm32\bin\ml /c /coff MsgBox.asm
c:\masm32\bin\link -lib *.obj /out:MsgBox.lib

Main program ( call_MBox.asm ):

      .model flat, stdcall
      option casemap :none   ; case sensitive

      include \masm32\include\windows.inc
      include \masm32\include\user32.inc
      include \masm32\include\kernel32.inc
      includelib \masm32\lib\user32.lib
      includelib \masm32\lib\kernel32.lib

      includelib MSGBOX.LIB         ; This is our library

      ; Declare the function prototype from our library

   cMsg     db 'My Message',0
   cTitle   db 'My Title',0

   invoke MBox, Addr cMsg, Addr cTitle
   invoke ExitProcess, 0
END Start

\masm32\bin\ml /c /coff Call_MBox.asm
\masm32\bin\Link /nologo /SUBSYSTEM:WINDOWS Call_MBox.obj

Hope it helps

RE: library in masm

Unfortunately it doesn't work in masm611 at "c:\masm32\bin\link -lib *.obj /out:MsgBox.lib" command there is a "/out : unrecognised option name ; option ignored. I'll try to tweak it in order to get it work. But does anybody has another example for masm611.

RE: library in masm

Try to build with this:

LIB *.obj /out:msgbox.lib
